I provide a range of cloud architecture services, including but not limited to:

• Cloud Strategy & Consulting: Helping businesses develop a tailored cloud strategy aligned with their goals.
• Infrastructure Design: Designing scalable and resilient cloud architectures using best practices.
• Migration Services: Assisting with the seamless migration of on-premises applications to the cloud.
• DevOps & Automation: Implementing CI/CD pipelines, IaC (Infrastructure as Code), and automation to streamline operations.
• Security & Compliance: Ensuring cloud environments are secure, compliant with industry standards, and follow best practices.
• Cost Optimization: Identifying opportunities to reduce cloud costs without compromising on performance.

• Cloud Platforms: AWS, Azure, Google Cloud
• Infrastructure as Code: Terraform, CloudFormation, Ansible
• Containers & Orchestration: Docker, Kubernetes, ECS
• High Performance Computing (HPC): Slurm, OpenMPI, CUDA, OpenMP, threaded applications
• CI/CD: Jenkins, GitLab CI, GitHub Actions, Azure Pipelines
• Monitoring & Logging: Prometheus, Grafana, ELK Stack, CloudWatch, ElasticSearch
• Security: IAM, VPC, KMS

On this GitHub profile, you'll find a selection of my work, including:

• Financial Data API: an Azure-based API that provides real-time financial data to clients. The API is built in Python, using Azure Functions, Azure Blob Stroage, and Azure Key Vault. It is available at https://financial-data.mathquantlab.com. Swagger documentation is on the way.
• XVA simulation using Monte-Carlo and CUDA: a high-performance computing (HPC) application that calculates XVA (Counterparty Risk) using Monte-Carlo simulations. The application is based on Python and CUDA to run simulations on GPUs, and is also written in C++ for CPU-based simulations. CUDA C++ code is coming soon.
• Open Source Contribution:
  • Rudy Morel's Scattering Spectra: a Python package designed to identify patterns in financial data using wavelets. I optimized parts of the code and fixed a bug related to the platform's compatibility.
  • Rudy Morel's Shadowing: a Python package designed to run Monte-Carlo simulations using the shadowing technique. I contributed to the codebase by optimizing the code and improving the documentation.

I'm currently focusing on:

• HPC cluster on Azure: a compute cluster that runs high-performance computing (HPC) workloads on Azure.
• Learning: Azure Solutions Architect Expert certification.
